98 k2500 jerking on deceleration
Hi everyone just purchased a 98 k2500 6.5 with a manual trans 230,000 miles truck seems to pull pretty decent with no problems 3rd its a bit of a dog had someone drive it and said it was way under power so far i have replaced the pmd and relocated it changed all 8 glow plugs along with the fuel filter the lift pump when I go to downshift with the rpms past 1500 it jerks really bad like im tapping the throttle really fast goes away when i push the clutch in when I had a mechanic check it out it jerked so bad that it almost died and went into a limp mode anytime you tried to give it throttle the rpms would go to 1500 and drop again and again shut the key off started it back up it was fine the truck pulled 2 codes one was a slow injection timing the other was a bad thermostat any help would be appreciated since I have called many diesel mechanics and no one knows what it is
